GrammAcc d63a88bef1 AssetLib: Fix long plugin names breaking the UI
The UI was extending past the screen width when loading a page diplaying
a plugin with an especially long title in the asset store plugin.

I implemented a new `EditorAssetLibraryItem::clamp_width` method that
checks that the title text is not longer than the column width minus
some padding and truncates it if it is.

I also noticed that the nav buttons for paginated results were causing the UI to extend past
the screen width on higher editor scales since they were hardcoded to
show ten page buttons if there were enough results. I modified the
pagination slightly to display a dynamic number of nav buttons based on
the editor scale in order to fix this other cause of the same problem.

I had to use the font of the `title`, which is a `LinkButton` in order
to determine the text width, so I added a public getter `get_button_font` to the `LinkButton` class.
